Step 1
Squaringon both sides
( 2 + 4 x ) 2 = ( 3 3 4 x ) 2 2 + 4 x = 9 + 3 4 x 6 3 4 x 6 3 4 x = 12 4 x 2 4 x 6 3 4 x = 10 8 x
Squaring on both sides
( 6 3 4 x ) 2 = ( 10 8 x ) 2 36 ( 3 4 x ) = 100 + 64 x 2 160 x 108 144 x = 100 + 64 x 2 160 x 64 x 2 16 x 8 = 0 8 x 2 2 x 1 = 0
Step 2
x = 2 ± 4 + 32 2 ( 8 ) = 2 ± 6 16 x = 2 + 6 16   (or)   2 6 16 x = 1 2   (or)   1 4
So the values of x are 1 2 ,   1 4
